Flask-RESTPlus: Solve the Chinese garbled problem of RESTful API

With the rapid development of the Internet, more and more web applications are beginning to utilize RESTful APIs to provide data services. When using RESTful API, the problem of Chinese garbled characters has become a headache for developers. Flask-RESTPlus was born to solve this problem.

Flask-RESTPlus is an extension of the Flask framework, which provides a set of RESTful API rapid construction tools based on the Swagger standard. Compared with Flask-RESTful, Flask-RESTPlus provides more functions and convenient methods to build RESTful APIs.

In Flask-RESTPlus, the Chinese garbled problem is caused by the parser. At this time, the parser needs to be set accordingly.

For Form and JSON parsers, we can use the following code to solve the Chinese garbled code problem:

from flask_restplus import reqparse

parser = reqparse.RequestParser()
parser.add_argument('name', type=str, location='form', help='名称')
args = parser.parse_args()

In the above code, we solve the Chinese garbled code problem by adding 'utf-8' encoding .

At the same time, we can also set up the parsers for XML and YAML in the same way.

from flask_restplus import reqparse

parser = reqparse.RequestParser()
parser.add_argument('name', type=str, location='xml', help='名称')
args = parser.parse_args()

In addition, Flask-RESTPlus is the same as the Flask framework. The encoding method settings can also be configured by modifying environment variables. We can configure the following in the main function:

import os

os.environ['RESTPLUS_MASK_SWAGGER'] = False # 设置为True会自动将所有Unicode字符转为ASCII
os.environ['LANG'] = 'en_US.UTF-8' # 设置编码方式

In the above code, we set the encoding method by modifying the environment variables. Among them, 'RESTPLUS_MASK_SWAGGER' converts all Unicode characters into ASCII characters, and 'LANG' is used to set the encoding method.

In short, Flask-RESTPlus provides a flexible configuration method that allows us to easily solve the problem of Chinese garbled characters. At the same time, it also provides a complete set of RESTful API building tools, allowing us to build web applications more efficiently.
